Localized outbreaks of pertussis are not uncommon and occur throughout the year. Some examples of current pertussis activity in the US include:
* From January 1 through December 31, 2010, 8,383 cases of pertussis (including ten infant deaths) were reported throughout California. This is the most cases reported in 63 years when 9,934 cases were reported in 1947 and the highest incidence in 52 years when a rate of 26.0 cases/100,000 was reported in 1958. Previously, the peak was in 2005 when there were 3,182 cases reported. Disease activity is slowing statewide, however relatively high numbers of cases continue to be reported each week. Data for 2010 is still preliminary and final case counts are not expected until Spring 2011...http://www.cdph.ca.gov/HealthInfo/discond/Pages/Pertussis.aspx

This is on top of a long term rising trend in the reported number of pertussis cases since about 1990. As of October 31, there were 1,092 cases reported for 2010. In 2009 (for the complete year) there were 902 cases reported. In 2008 there were 315 cases reported...
